Find the population density of a city with an area of 598 square miles and a population of 21,500 people.

Pie

Answer: $35.12\text{ persons per square mile}$

Step-by-step explanation:

Given: The area of a city = 598 square miles

The population of city = 21,500 people.

The population density for a city is given by :-

$\text{Population density }=\frac{\text{Number of people }}{\text{Land area}}\\\\\Rightarrow\ \text{Population density }=\frac{21000}{598}\\\\\Rightarrow\ \text{Population density }=35.11705\approx35.12\text{ persons per square mile}$

Hence, the population density of a city = $35.12\text{ persons per square mile}$

If line ON is congruent to line OL find the measure of angle OML

snow_lady [41]

Angle n and angle l have the same degree so set them equal to eachother
7x+8=9x-8
-7x both sides
8=2x-8
+8 both sides
16=2x
÷2 both sides
x=8
solve for angle l
9 (8)-8
72-8=64°
solve for angle OML
90+64+OML=180
154+OML=180
-154 BOTH SIDES
OML=26°
